PawLIB is our standard library, which all of our major projects (Anari, Lightrift, Punchline, Trailcrest, Ratscript, and SIMPLEXpress) will rely upon.
Any code that is generally reusable should be migrated to PawLIB. However, all PawLIB code should be general-purpose. Code written specifically for a single project's needs will probably need to live with that project.
PawLIB is maintained by the entire programming department at MousePaw Media, so it doesn't technically fall into the jurisdiction of any one team or individual. @jcmcdonald is the final word on PawLIB in general, but everyone is encouraged to help maintain the library.
